Make the default build options a more preferred set, such as making
BPF skeletons default and failing the build if jevents or libtracevent
dependencies fail. The binutil dependencies are opt-in given license
restrictions. abi::__cxa_demangle demangling support is added so that
libiberty, from binutils, isn't necessary for C++ demangling.
Some build/test dependencies are fixed and the code cleaned up.
Ian Rogers (13):
perf build: Support python/perf.so testing
perf build: Make BUILD_BPF_SKEL default, rename to NO_BPF_SKEL
perf build: Remove unused HAVE_GLIBC_SUPPORT
perf build: Error if no libelf and NO_LIBELF isn't set
perf util: Remove weak sched_getcpu
perf build: Error if jevents won't work and NO_JEVENTS=1 isn't set
perf build: Make binutil libraries opt in
tools build: Add feature test for abi::__cxa_demangle
perf symbol: Add abi::__cxa_demangle C++ demangling support
perf build: Switch libpfm4 to opt-out rather than opt-in
perf build: If libtraceevent isn't present error the build
tools headers: Make the difference output easier to read
perf build: Remove redundant NO_NEWT build option

Add a build target to echo the python/perf.so's name from
Makefile.perf. Use it in tests/make so the correct target is built and
tested for.

BPF skeleton support is now key to a number of perf features. Rather
than making it so that BPF support must be enabled for the build, make
this the default and error if the build lacks a clang and libbpf that
are sufficient. To avoid the error and build without BPF skeletons the
NO_BPF_SKEL=1 flag can be used. Add a build-options flag to 'perf
version' to enable detection of the BPF skeleton support and use this
in the offcpu shell test.

HAVE_GLIBC_SUPPORT is only used in `perf version --build-options` but
doesn't control any behavior. Remove from the build to simplify it.

functionality. Require that the NO_LIBELF=1 build option is passed if
this is intentional.

sched_getcpu may not be present and so a feature test and definition
exist to workaround this in the build. The feature test is used to
define HAVE_SCHED_GETCPU_SUPPORT and so this is sufficient to know
whether the local sched_getcpu is needed and a weak symbol can be
avoided.

Rather than disabling jevents if a sufficient python isn't present
error in the build. This avoids the build progressing but the binary
being degraded. The build can still succeed by specifying NO_JEVENTS=1
to the build and this is conveyed in the error message.

binutils is GPLv3 so distributions cannot ship perf linked against
libbfd and libiberty as the licenses are incompatible. Rather than
defaulting the build to opting in to libbfd and libiberty support and
opting out via NO_LIBBFD=1 and NO_DEMANGLE=1, make building against
the libraries optional and enabled with BUILD_NONDISTRO=1.

cxxabi.h is part of libsdtc++ and LLVM's libcxx, providing
abi::__cxa_demangle a portable C++ demangler. Add a feature test to
detect that the function is available.

Refactor C++ demangling out of symbol-elf into its own files similar
to other languages. Add abi::__cxa_demangle support. As the other
demanglers are not shippable with distributions, this brings back C++
demangling in a common case. It isn't perfect as the support for
optionally demangling arguments and modifiers isn't present.

If libpfm4 passes the feature test, it would be nice to have it
enabled rather than also requiring the LIBPFM4=1 build flag.

If libtraceevent isn't present, the build will warn and continue. This
disables a number of features and so isn't desirable. This change
makes the build error for this case. The build can still be made to
happen by adding NO_LIBTRACEEVENT=1.

Add failures to an array and display it before exiting. Before:
```
Warning: Kernel ABI header at 'tools/include/uapi/linux/fcntl.h' differs from latest version at 'include/uapi/linux/fcntl.h'

```
After:
```

The option controlled nothing and no code depends, conditional or
otherwise, on libnewt.

Sure, you can do something similar here but you need to add "diff -u"
at the beginning of the line. We could add a flag to the tool to do
the diff for you. The current 1st warning line is ~120characters long
and wraps onto 2 lines for me, the diff makes this 3 lines. Overall I
struggle to see the Makefile.config warnings because of all the
check-headers.sh warnings and the indent makes the grouping,
check-headers.sh vs other warnings/error, easier to see.
Compare the new output:

That said there are more warnings with the new code, which looks like
some of the filters have kept working as they should :-)

Right, this is kind of the point of the patch set. Make it harder for
people to make a reduced perf binary without explicitly flagging that
this is what they want. For the build tests it may be better to make
the flag conditional on what is installed in the image.

Sorry, I was testing this on top of:
https://lore.kernel.org/lkml/20230116010115.490713-1-irogers@google.com/
The issue being that we're trying to use an old libbpf that the has
meant disabling things but:
NO_BPF_SKEL := 1
hadn't been set as part of this. I can address in v2, but with the
"assume libbpf 1.0+" patch I hadn't been worrying about this as we'd
error out for this case - rather than build error. The erroring out
can be worked around by just not having libbpf be dynamic (ie static
or not at all by adding NO_LIBBPF=1).
Thanks,
Ian

Yeah, I'll tweak the warning:

I'll continue fixing more stuff, like adding NO_LIBTRACEEVENT=1 to
things like amazonlinux devel, that still doesn't package libtraceevent,
but so far...

This one seems to have an old libtraceevent, so this message:
Makefile.config:635: No libunwind found. Please install libunwind-dev[el] >= 1.1 and/or set LIBUNWIND_DIR
Makefile.config:1046: No libbabeltrace found, disables 'perf data' CTF format support, please install libbabeltrace-dev[el]/libbabeltrace-ctf-dev
Makefile.config:1137: libpfm4 not found, disables libpfm4 support. Please install libpfm4-dev
Makefile.config:1155: *** ERROR: libtraceevent is missing. Please install libtraceevent-dev/libtraceevent-devel or build with NO_LIBTRACEEVENT=1. Stop.
Has to change a bit, like for libbpf, I'll check

Hi Ian,
I think cross compilation for arm on x86 isn't working after this change
(at least on Ubuntu).
Even with all of the arm64 libstdc++ stuff installed, you can only link
to it using g++, but the perf build tries to link to it using gcc. Not
sure it's some quirk with the search paths on Ubuntu or something else:
$ aarch64-linux-gnu-gcc -lstdc++
/usr/lib/gcc-cross/aarch64-linux-gnu/12/../../../../aarch64-linux-
gnu/bin/ld: cannot find -lstdc++: No such file or directory
collect2: error: ld returned 1 exit status
g++ gets further:
$ aarch64-linux-gnu-g++ -lstdc++
...
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status
At the end of the perf build it looks like something similar is
happening (with all the non interesting bits deleted):
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -C tools/perf
NO_BPF_SKEL=1 V=1
aarch64-linux-gnu-gcc ... -o perf
/usr/lib/gcc-cross/aarch64-linux-gnu/12/../../../../aarch64-linux-gnu/bin/ld:
cannot find -lstdc++: No such file or directory
If I build with NO_DEMANGLE=1 then the build works, but I think it would
at be best to autodetect rather than have to do this. Or maybe even link
at the end with g++ if we're going to use libstdc++?
Thanks
James

Hi James,
sorry for the problems you are having, I'll see if I can get a repo. I
did add a feature test with this change in the same set:
https://lore.kernel.org/lkml/20230311065753.3012826-9-irogers@google.com/
So it should be feature testing and only enabling when
HAVE_CXA_DEMANGLE_SUPPORT is present. Obviously something is up, so
I'll have a think about it.
Thanks,
Ian

If you have NO_LIBELF=1 it sets NO_DEMANGLE=1 automatically so it skips
the c++ linking step. If you run with V=1 you can see that it doesn't
have -lstdc++ on the last link line.
But, having said that, I went to make a full reproducer in docker but it
actually worked. Turns out that the issue was on my end. I'd used
update-alternatives for a different compiler version and looks like I
had half of one gcc and half of another g++. Completely my fault, sorry
for the noise!
